a good clean in lukewarm water and dishwashing liquid to clean
away oils and stray metal.

3. Metal primer creates a strong bond between paint and
metal parts to reduce chipping and flaking. Many cast
metal parts need careful cleaning with files and sandpaper.

fine for use on scale models when it
can be fogged on in one or two light
coats, just enough to cover the part.
